A number of authors have studied Lagrangian Floer theory and homological mirror symmetry in finite characteristic in recent years, see e.g. [1]}, [2]}, [3]}, [4]}.
It has not possible to carry on this study for compact Calabi–Yau varieties of dimension \(\ge 3\) , because the available constructions of the Fukaya category relied on a characteristic-zero assumption (c.f. [5]}, [6]}, [7]}, [8]}). Our construction in this paper removes this obstacle.
